Specification of Letters Patent.

7 Patented. March 20, 1906.

Original application filed May 12,1905, Serial No. 260,149. Divided and this application filed September 7,1905. Serial No. 277,301-

To ally/ham it may concern:

Be it known that I, AUGUSTUS H. Woof)- RUFF, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Locks and Gravity-Bolts for Windows; and I do hereby declare the following to-be a full, clear, and

exact description of the invention, Such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

My present invention relates generally to improvements in looks and gravity-bolts for use with WlIldOWS, skylights, and the like, and is in the nature of a division of my former application for Letters Patent, filed May 12, 1905,.SerialNo. 260,149. x

The invention relates more particularly to a novel form of lock including a gravity-bolt, with means for pushing the same back and at the same time for opening the window.

The invention therefore has for its principal object to provide a simply-constructed and efficiently operatin lock and gravitybolt, all arranged for ho ding a window or the like in its closed position, but which is provided with means for pushing the bolt ack for opening the window or the like, all with a view of providing a device which can be readily manipulated and with a view of dispensing with the use of springs, which are apt to become weak and useless.

. A further object of this invention is to pro- .vide a bolt working from the top and inside of the frame, so as not to become clogged with dirt or by paint sticking the bolt fast, and, furthermore, to provide a novel and simple means for effectively opening and closing a fixture, as a window, skylight, door,

and the like, which when closed is positively held in its closed position by means of the gravity-bolt.

With the Various objects of my present invention in view the same consists in the novel construction of lock and gravity-bolt for a fixture such as'a-window, skylight, door, shutter, and the likewith'mean's for pushing the bolt back for opening the winvdowand the like; and, furthermore, this in. vention consists in the various arrangements well as in the details of the construction of the same, all of which will be hereinafter more fully described and then finally embodied in the clauses of the claim, which are appended to and which form an essential part of this specificationj The invention is clearly-illustrated in the accompanying drawings, in which Figure 1 is a transverse vertical section of a metallic or other suitable window-frame and window and of the said lock and gravitybolt and means for ushing back the same, showing the window eldopen; and Fig. 2 is 'a similar sectional representation of the same arts, but showing the window held in its ocked orclosed position by the gravity-bolt in the upper part ofthe window-frame. Fig. 3'is a vertical section, on an enlarged scale,

of the upper portionvof the window-frameand window-sash, showing the gravity-bolt in its locked engagement, with the parts in the lock-casing being shown in elevation,

while other parts in said lock-casing are represented in section. Fig.4 is a top view of the gravity-bolt and guide-plate in which it is movably arranged. Fig. 5 isia detail ver tical' section of the lock-casing and part of a window-frame, said section being taken on line 5 5 in saidjFig. 3 looking in the direction of the arrow X, the latch of thelocking mechanism, however, beingshown in its raised position. Fig. 6 is a sectional representation of a lock-casing provided with a lock mechanism of a slightly-modified form of construction, but still embodying the principles of the present invention.

Similar characters of reference are employed in all of the said above-described views to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference character 1 indicates a metallic or other suitable window-frame of any usual construction, which is, provided One or more window-sashes 6, preferably made of sheet metal, are pivotally suspended or swung in the opening of the window-frame, each sash having an upper hollow portion 7 and a lower hollow portion 8, respectively provided with the channel-shaped receiving edges 9 for securing the usual window-glass 10 between said upper portion 8 and lower portion 9. Suitable stops 11 may also be provided at the back on opposite sides of the opening in the window frame 1, against which the window-sash is swung when opened to limit the pivotal movement of the window, as clearly shown in Figs. 1, 2, and 3 of the drawings.

Suitably secured in the upper hollow portion 7 of the window-sash during the process of bending the sheet metal into shape is a lockcasing and its mechanism contained therein, as clearly indicated in the several figures of the drawings. This casing usually consists of two sections 12 and 13, as indicated in Fig. 5 of the drawings, each section being provided with a perforated flange 14, screwbolts 15 and nuts 16 being employed for securing the sections of the lock-casing against the inner face of one'of the sides of the portion 7, substantially as shown in Figs. 3 and 5 of the drawings. One of said sections, as 12, is provided with screw-receiving holes 17, while the other section 13 is formed with interior posts 18, provided with screw-threaded sockets 19, placed directly opposite the screwholes 17 for the reception of screws 20, by means of which the two sections 12 and 13 are secured together, as shown. A cover or plate 21, provided with a holding-flange or lugs 22, is arranged over the upper open portion of the two connectedsections 12 and 13, the said cover or plate 21 being held in place by said flange or lu s 22 and by the inner face of the upper walfof said portion 7. The said cover or plate 21 is provided with an opening 23, and in said upper wall of the portion 7 is a correspondingly-formed opening 24, which registers with the said opening 23, and thereby forms one continuous openin through said upper wall of the portion 7 an said cover or plate 21. Pivotally arranged upon the upper post 18 of the said section 13 is a latch 25, having a recess 26 in its pivoted portion and provided with a lifting end or portion 27. Normally the said latch is in the position indicated in Figs. 2 and 3 of the drawings; but when the window is opened said latch is actuated in the manner to be hereinafter more fully described, whereby its lifting end or portion 27 is moved into the opening formed by the openings 23 and 24, previously mentioned, as clearly indicated in %otted outline in said Fig. 3 and in section in Suitably secured upon the inner face of the base of the hollow portion 2 of the frame 1 is a plate 28, provided with an upwardly-extending guiding-socket 29. 'This socket is preferably of an angular configuration in cross-section, as indicated in the dotted outline in said Fig. 6, which is preferably wider at the top than at the bottom and has a pin 30 extending across its guiding opening. Movably arranged within the said guidingsocket is a bolt 31, having an elongated opening 32, through which the said pin 30 extends and upon which the said bolt is movably ar ranged. The lower holding portion of said bolt has a rounded edge 33, and upon its upper end it may be provided with a head or enlargement 34, which normally rests upon the upper marginal edge of the said guidingsocket 29 and by gravity forces the lower holding portion of the bolt 31 into and through the previously-1nentioned openings 23 and 24 to retain the window-sash in its closed relation in the window-frame in the manner clearly indicated in Figs. 2 and 3 of the drawings.

Referring now more particularly to Fig. 3 of the drawings, it will be seen thatin the front and rear walls of the said upper hollow portion 7 of the window-sash I have placed suitablydisposed and upwardly-inclining openings 35 and 36, respectively, the two sections 12 and 13 being respectively provided with semicircular or other suitably-shaped guide portions 37 and 38, in which is movably arranged an upwardly-extending and angular]y-inclining tube 39, provided with a teat or projection 40, which extends in operative engagement into the recess 26 of the latch 25. Within the said tube 39 is a rod 4]., having an upper shouldered portion 42, which has a screwthreaded part 43 for the screwing thereon of a nut 44. The lower end portion of the said rod 41 extends from the opening 35 in the front piece of the portion 7 of the windowsash and is provided with a receiving eye or loop 45. From an inspection of the drawings it will be seen that the said nut 44 rests upon the upper edge of the tube 39 to prevent the displacement of the said. rod 41 from said tube 39. It will also be noticed that the weight of the pivoted latch 25 under normal conditions (indicated in Fi 3 of the drawings) retains the tube 39 and parts connected therewith in the raised position shown in said figure.

Suitably connected with the receiving eye or loop 45 of the said rod 41 is a flexible connection 46, such as a rope or chain, by means of which the tube 39 is actuated to operate the latch 25 and lifts the gravity-bolt 31 from its holding engagement with the windowsash in the manner to be presently described.

The operation of the device will be clearly understood from aninspection of Figs. 1, 2, and 3 of the drawings and need not be more particularly described. Suflice it to say that when a pull is exerted upon the flexible connection 46 the tube 39 and rod 41 receive a ed end of they bolt 31.

portion of the bolt 31 is thus pushed upslight'movement in an angularly downwarddirection, causing the projection 40. to swing the latch upwardly. and against the round- The said lower end wardly from its holding engagement with the openings 23 and 24, and the window-sash is swung into its opened relation, in which it is held by the fastening of the flexible connection 46 to a hook or other object in any usual manner. When the flexible connection is'agai'n released, the sash and its window at once return to the closed position in the frame 1, as clearly indicated in Fig. 2, the

gravity-bolt 31 being first raised by contact.

with the upper portion of the sash '6. The

bolt immediately drops back into the holes or openings 24 and 23, and thereby positively retains the closed window in its locked relation in the frame 1. It will also be seen that the said shield or rain-drip 5 protects the nut 44 and tube 39 against corrosion by preventing the rain from: beating upon the hut and dripping down into the said tube 39.

In Fig. '6 of the drawings I have shown a slightly-modified arrangement and construe.-

- tion of lock mechanism. In this construction, in which the general construction of the parts is practically the same as that hereinabove described, the tube 39 is movably arranged upon a long support 47, which extends from the opening to the opening 38 in the 0 posite sides of the casing. The latch 25 int s construction is also ofa slightly-' difierent configuration, the same being ro vided with a long curved edge 48,upon w 'ch the holding end of the bolt 31 rides, as indicated in the dotted outline in said Fig. 6 of the drawings, and is raised and lowered in a manner similar to that previously described;
